If you thought that a bike had to be jarring and unforgiving in order to be fast, we apologize in advance for bursting your bubble. The more comfortable you are, in fact, the faster you'll go. And if you need proof of this, look no further than our Ruby Expert with Ultegra Di2. Its revolutionary design erases any shadow of a doubt that smoother is indeed faster.

The frame is among the lightest that we've ever made, and it's been constructed from our superlative FACT 10r carbon fiber. Its stiffness levels are also off the charts, and compared to the SL4 iteration of yesteryear, you'll experience a whole new, faster, and more efficient geometry. Through some engineering sorcery, however, we've managed to keep the same fit, feel, and position that we've all come to love from the SL4's Women's Endurance Geometry. Of course, you're probably thinking, "get on to the suspension thing up front."

We call it Future Shock, and essentially, it's a piston in the head tube with 20mm of travel. We developed this technology in partnership with McLaren Applied Technologies, and the result of this are a host of drastic performance improvements, namely in the vertical compliance department. Without giving a physics lecture, we found that focusing on vertical compliance, instead of fork splay, meant that we could improve smoothness, speed, and comfort in one fell swoop. And of all the bikes that we've tested with our Rolling Efficiency Model, the new Ruby outperforms anything on the market.

- Featuring our Rider-First Engineered design that ensures every frame size has the same legendary responsiveness and smooth ride quality that you'd expect from a Ruby. The FACT 10r frameset is exceptional in every way, offering the ideal blend of light overall weight and targeted stiffness. Meanwhile, the all-new Future Shock "suspension" system at the cockpit delivers a revolutionary degree of comfort and control.

- The Ruby Disc fork is built from our extraordinary FACT carbon fiber for the lightest possible weight, supreme stiffness, strength, and reactivity, while a thru-axle design only stands to bolster all of the above.

- Comes equipped with a 25lbs spring installed (color: black, weight: medium), and also includes both 13lbs (color: blue, weight: soft) and 40lbs (color: yellow, weight: firm) springs that can be installed to match the terrain you're riding.

Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are some benefits of electronic shifting that you don't want to miss.

Shifting Performance

Electronic shifting systems use powerful servo motors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with surgical precision and without chain rub.

Customization

Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.

Dependability

Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you'll never have to replace a derailleur cable ever again.
